Function Documentation

ChimeraHost* host_decode (  ChimeraState *  state, char *  s )

host_decode: decodes a string into a chimera host structure. This acts as a host_get, and should be followed eventually by a host_release.

void host_encode (  char *  s, int  len, ChimeraHost *  host )

host_encode: encodes the host# into a string, putting it in s#, which has len# bytes in it.

ChimeraHost* host_get (  ChimeraState *  state, char *  hostname, int  port )

host_get: gets a host entry for the given host, getting it from the cache if possible, or alocates memory for it

void* host_init (  void *  logs, int  size )

host_init: initialize a host struct with a size# element cache.

void host_release (  ChimeraState *  state, ChimeraHost *  host )

host_release: releases a host from the cache, declaring that the memory could be freed any time. returns NULL if the entry is deleted, otherwise it returns host#

void host_update_stat (  ChimeraHost *  host, int  success )

host_update_stat: updates the success rate to the host based on the SUCCESS_WINDOW average
